Good text Heiko, thanks.

Re OPEN TO DISCUSS proxy-mode; technically it is not possible to adapt anything inside an HTTPS link. All the proxy can see is a source IP address, a destination IP address and a stream of encrypted bytes. That's why any HTTPS adaptation *has* to be done in link-mode.

Thanks,

Rob

Hi All,

Please see below:

3.3.6.2: 
New:
Due to the nature of a transforming proxy, there will not be end to end security for HTTPS, when content transformation will be applied.

If the response contains links whose URIs have the scheme https the proxy may only rewrite them so that it can transform the content, if it meets the following provision: 

If a proxy does rewrite such links, it must advise the user of the security implications of doing so and must provide the option to avoid decryption and transformation of the resources the links refer to, by bypassing the CT proxy for accessing the original content without touching the proxy.

Note: If the user decides for the latter option, the session might never return back to content transcoding, based on the technical integration of the CT proxy (link mode)

OPEN TO DISCUSS: How about proxy mode integration??? Do we need to menntion those tech integration options?
